  • Patent number: 12613820
    Abstract: A bus slave device and an interrupt request determination method thereof are provided. The bus slave device sets interrupt request groups and interrupt request numbers to slave devices, respectively. A master device receives an interrupt request through an alarm pin, and each of the slave devices send interrupt request through the alarm pin, and an alarm detection module detects whether the alarm pin is at a low level. A selecting module selects an interrupt mode which is one of a level mode and a pulse mode. An interrupt request module sends or terminates the interrupt request. The master device configures the interrupt request group and the interrupt request number corresponding to the slave devices through the control module to generate a master device receiving signal, and transmits the master device receiving signal to the master device through the data pin and the clock pin.

  • Patent number: 12001556
    Abstract: An anti-virus chip includes a first connection terminal, a second connection terminal, a detection unit and a processing unit. The first connection terminal and the second connection terminal are respectively coupled to a connection port and a system circuit of an electronic device. The detection unit detects whether the connection port is connected to an external device via the first connection terminal. When the detection unit detects that the connection port is connected to the external device, the processing unit performs a virus-scan program on the external device to determine whether a virus exists in the external device. When determining that a virus does not exist in the external device, the processing unit establishes a first transmission path between the first connection terminal and the second connection terminal. When determining that a virus exists in the external device, the processing unit does not establish the first transmission path.
